So it turns out I already knew how to build a buffer – every boost, drive or fuzz pedal I've made so far is designed around that idea.

There are some great resources on the AMZ site: https://www.muzique.com/
In particular, the MOSFET boost is well worth building: http://www.muzique.com/schem/mosfet.htm

Some books I recommend
Small signal design - Douglas Self
Opamp cook book - various versions but once you see how versatile opamps are there's enough cookbooks to keep you in designs for years

The spec sheet there includes application schematics, but basically you chuck 9v in and get either -9v out or 18v (ish) so you get much more headroom in the circuit you're powering.
Opamp followers are a really basic configuration.
